Yes, I am having this problem as well. (also since updating WatchOS to 7.3.2).
Details from the error on Devices and Simulators window:

[myAppleID] does not have access to Symbols for watchOS 7.3.2 (18S821)**************
I updated iOS on iPhone. Xcode and MacOS are both up to date.
I use a personal AppleID on all my devices, and have a separate Developer ID for Xcode. So, I went through the process of switching to the developer ID on MacOS (it is already in Xcode).
Called developer support twice. They suggested filing a TSI (was hoping to find answer here).
I'll be going through that process for my iPhone and Watch too and see if that makes a difference, then submit TSI.
